The Samsung UN55D6300SF 55" LED TV was a cinch to crack open and disassemble. It has standard Phillips screws and easily-accessable parts. Provided you can get replacement parts, this TV shouldn't be too difficult to repair.

Inside the case, you'll find the LCD assembly, motherboard, LCD control board, power supply board, front control panel PCB, and a handful of screws and cables. As expected, this TV has lots of chips from Samsung. But, you'll also find chips from Realtek, STMicroelectronics, Intersil, AKM, Weltrend, Silicon Image, and Texas Intruments.
